MAINTENANCE
Your G-Series loudspeakers have been rigorously tested before they leave our factory, to ensure that they give you a lifetime
of flawless operation. Should any of your drive units fail and need replacing, please follow the guidelines below.
G6: LF & HF Drive Units
1.
Remove the six screws holding the grille in place. Carefully remove the grille from the front of the enclosure, taking
care not to distort the shape.
2.
For the LF drive unit, remove the four bolts holding it in place. For the HF drive unit, remove the four screws. Ensure
you have collected both the shake-proof and flat washers for each bolt. Gently lift the drive unit out of its locating hole
– please take care as it is heavy! Carefully disconnect the cables from the drive unit.
3.
To reinstate the driver, simply reverse the above procedure. Please observe the correct polarity – red cable to positive
terminal, black cable to negative (LF) or white cable to positive, yellow cable to negative (HF).
4.
Reinstate the grille by replacing it over the front of the enclosure, and reinstate the six screws taking care to use the
original holes.
G8: High Frequency Drive Unit
1.
Remove the six countersunk bolts with an Allen key, and using a flat blade screwdriver carefully ease the grille out of
location. Take care not to damage the LF driver.
2.
Using a 4mm Allen key, remove the four M5 socket-head bolts holding the HF waveguide in place. Lift the HF assembly
out of the enclosure and carefully disconnect the cables, observing correct polarity for future reference. The drive unit
can be removed using an 8mm spanner to release the locking nuts holding the driver to the waveguide.
3.
To reinstate the drive unit, reconnect the cables (white cable to positive terminal, yellow cable to negative), sit the
waveguide back in place before reinstating the four socket-head bolts. Avoid over-tightening these bolts as this may
crack the waveguide.
Note also the dispersion orientation of the waveguide
– the larger dimension of the
waveguide indicates the 90-degree dispersion plane.
4.
Reinstate the grille into place and reinsert the six countersunk bolts.
G8: Low Frequency Drive Unit
1.
Follow the above procedure to remove the grille.
2.
Using a 4mm Allen key, remove the eight M5 socket head bolts holding the driver in place. Lift the driver out of the
enclosure and carefully disconnect the cables.
3.
To reinstate the driver, attach the cables (red to positive terminal, black to negative) and reposition the driver.
Reinstate the eight bolts and retighten.
4.
Replace the grille be easing into place and reinstating the six countersunk bolts.
